Hi Cross posting to support as this is a support question.
Warning: ini_set() has been disabled for security reasons in
/usr/export/www/vhosts/funnetwork/hosting/kiran92/drupal/sites/default/setti ngs.php
on line 102
It seems that your host disable the use of ini_set, so you have to comment out all lines et the end of setting.php begining by ini_set.
Fatal error: Table 'kiran92_03.main_users' doesn't exist query: SELECT u.*, s.* FROM main_users u INNER JOIN main_sessions s ON u.uid = s.uid WHERE s.sid = '21ef666f5ff27a21ddfd88806c9abc2e' AND u.status < 3 LIMIT 0, 1 in

It seems that your DB isn't set up properly as the table main_users doesn't seem to exists. Did you add some prefix before tables ?
